Side airbags
Description of side airbags

The
airbag system is not a substitute for the seat
belts.

Fig.
232 Side airbags: Location in driver's seat (example)
The side airbags are located in the backrest
pad­

ding of the front seats.
In conjunction with the three-point seat belts,
the side airbags give the occupants additional
protection for the whole upper part of the body

(i.e.
the chest, stomach and pelvis) in the event
of
a
severe side collision
•=> A
in Important safety
notes on the side airbag system on page 285.
In a side collision the side airbags reduce the risk
of injury to the areas of the body facing the im­
pact.
How the side airbags work
When fully inflated, the side airbags reduce the
risk of injuries to the upper part of the
body.

Fig.
233 Side airbags in inflated condition
In certain types of side collision, the side airbag
(front) is triggered on the impact side of the
vehi­

cle
^Fig.
233. Further airbag systems may also
be triggered, depending on the circumstances.
When the system is triggered, the airbag is filled
with propellant gas.
In order to provide the desired extra protection in
an accident, the airbags have to inflate extremely
rapidly (within fractions of
a
second).
The fully deployed airbags cushion the impact for
the occupants and help to reduce the risk of in­
jury to the upper part of the body on the side fac­
ing the door.
Important safety notes on the side airbag
system

There
are a number of safety points concerning
the airbag system which you should remember.
This will help to reduce the risk of injury in an ac­
cident.
WARNING
-If
you
do
not
wear
a
seat belt, if
you
Lean

forward,
or are not seated correctly while
the vehicle is in motion, you are at greater
risk of injury should the side airbags be
trig­

gered in an accident. This applies particular­
ly to children if they are not properly protec­
ted by
a
child restraint system.
- If children are not seated correctly, they are
at greater risk of injury should the airbag
system be triggered in an accident. This is
particularly the case if the child is travelling
on the front passenger's seat and the airbag
system is triggered in an accident. This
could result in serious or potentially fatal in­
jury
^>page
267, Child seats.
- It is important not to attach any accessories
(such as cup holders) to the doors. This
would impair the protection offered by the
front side airbags.
- The sensors for the airbags are located in
the front doors. You must therefore not
make any modifications to the doors or door
trim (e.g. retrofitting loudspeakers),
as
this
could impair the function of the side air-

bags.
Any damage to the front doors could
285

Airbag system
lead to faults in the system. Repairs or any
other work on the front doors must there­
fore always be carried out by
a
qualified
workshop.
- The built-in coat hooks* should only be used
for lightweight clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
- Do not apply excessive force to the sides of
the backrests (such as hard knocks or kicks),
as this could damage parts of the system.
The side airbags could then fail to operate
when required.
- If
you
intend to fit protective covers over
the seats, these must be of the specific type
approved for use on Audi seats with side air-

bags.
Conventional seat covers would ob­
struct the side airbag when it inflates out of
the backrest, and seriously reduce the air-
bag's effectiveness.
- Any damage to the original seat upholstery
or around the seams of the side airbag units
must be repaired immediately by a qualified
workshop.
- Any work involving the side airbag system or
removal and installation of the airbag com­
ponents for other repairs (such as repairs to
the seats) must always be performed by a
qualified workshop. Otherwise the airbag
system may fail to work properly.
© Note
All the other airbags in the car will remain
functional if the front passenger's airbag has
been deactivated.
Head-protection airbags
Description of head-protection airbags



Fig.
234 Location of head-protection airbags above the
doors (example)
The head-protection airbags are located above
the doors on the left and right sides of the
vehi­

cle.
The locations of the airbags are marked with
the word "AIRBAG".
In conjunction with the three-point seat belts
and side airbags, the head-protection airbags
give the occupants additional protection against
head and neck injuries in a severe side collision

•=>
A in Important safety notes on the head-pro­
tection airbags on page 287.
Together with other design features (including
cross-braces in the seats and the overall strength
of the body structure), the head-protection and
side airbag system offers an effective further im­
provement to occupant protection in side im­

pacts.

How the head-protection airbags work
When fully inflated, the airbags reduce the risk
of head or chest injury in a side collision.

The head-protection airbag system is triggered in
certain types of side collision
^>Fig.
235. Further
airbag systems may also be triggered, depending
on the circumstances.
When the system is triggered, the airbag fills
with a propellant gas and covers the entire area
in front of the side windows, including the door
pillars. The head-protection airbag inflates to
soften the impact if an occupant strikes parts of
the interior or objects outside the vehicLe with
their head. By reducing the head impact and re­
straining uncontrolled movement of the head,
the airbag also reduces the forces acting on the
neck.
In order to provide the desired extra protection in
an accident, the airbags have to inflate extremely
rapidly (within fractions of
a
second).
Important safety notes on the head-
protection airbags

There
are a number of safety points concerning
the airbag system which you should remember.
This will help to reduce the risk of injury in an ac­
cident.
A WARNING
- It is important to ensure that the area
around the openings for the head-protec­
tion airbags remains unobstructed at all

times,
so that the airbags can infLate prop­
erly if needed.
- The built-in coat hooks should only be used
for lightweight clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
When using the coat hooks, do not hang the
clothes on coat hangers.
- The space between the passengers and the
head-protection airbags must never be oc­
cupied by children, other passengers or

pets.
Passengers should never lean out or
put
a
hand
or
arm out of the window while
the vehicle is in motion.
- Do not move the sun visors out to cover the
side windows if there is anything attached
to them (such as pens or
a
garage door
opener). These objects could cause injury if
the head-protection airbag is triggered.
The sensors for the airbags are Located in
the front doors. You must therefore not
make any modifications to the doors or door
trim (e.g. retrofitting loudspeakers),
as
this
could impair the function of the side air-

bags.
Any damage to the front doors could
Lead to faults in the system. Repairs or any
other work on the front doors must there­
fore always be carried out by
a
qualified
workshop.
Sun blinds fitted on the rear doors must not
obstruct or impair the airbags in any way.
If unsuitable accessories are installed near
the head-protection airbag, the protection
afforded by the airbag can be seriously im­
paired if the system is triggered. When the
head-protection airbag opens, parts of
these accessories could be thrown into the
vehicle and injure passengers
^>page
340.
Any work involving the head-protection air-

bags,
or removal and installation of the air-
bag components for other repairs (such as
repairs to the roof liner), must always be
performed by
a
qualified workshop. Other­
wise the airbag system may fail to work
properly.

A WARNING

- If
you
have no alternative but to install a
rearward-facing child seat on the front pas­
senger's seat, the front passenger's airbag
must be deactivated beforehand. Potential­
ly fatal injuries to the child can result if the
front passenger's airbag is not deactivated

•=>

- If
you
have deactivated the front passeng­
er's airbag, reactivate it as soon as the child
seat is no longer needed so that the airbag
can continue to give the required protec­

tion.

- It is the driver's responsibility to ensure that
the key-operated switch is set to the correct

position.

Fuel
Petrol grade
Applies to: vehicles with petrol engine

The
correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic converter
and must only be run on unleaded petrol. Petrol
must be sulphur-free and must comply with the
EN 228 standard. You can fuel your vehicle with
fuels containing a maximum of 10%
ethanol

(E10). The petrol grades have different octane
ratings (RON).
The following headings relate to the sticker on
the inside of your vehicle's tank flap:
Unleaded fuel only RON/ROZ
95
Super,
Premium or
min.
RON/ROZ 91 Normal
The use of premium petrol (95 RON) is recom­

mended.
If
that
type of fuel is not available,
reg­

ular petrol (RON 91) can be used with a slight
loss of power.
Unleaded fuel only, min. RON/ROZ
95

Super, Premium
Premium petrol (at least 95 RON) must be used.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an
emer­

gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­

ble.

Unleaded fuel only RON/ROZ 98 Super Plus
or min. RON/ROZ 95 Super, Premium
The use of Super Plus petrol (98 RON) is recom­

mended.
If
that
type of fuel is not available, pre­
mium petrol (RON 95) can be used with a slight
loss of power.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an
emer­

gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­

ble.

© CAUTION
- Do
NOT fuel
your vehicle with
high-ethanol

fuel blends (e.g. E50 or E85). This will dam­
age the fuel system.
- just one tank of leaded fuel or fuel with
metallic additives will permanently impair
the efficiency of the catalytic converter.
- You should use only petrol additives which
have been approved by Audi. Additives with
so-called octane boosters or antiknock
addi­

tives can contain metallic additives that
cause significant damage to the engine and
the catalytic converter. Do not use such ad­
ditives.
- Metal-based fuels, which can be identified
from the marking on the fuel dispenser,
must not be used. LRP fuel (lead replace­
ment petrol) also contains high concentra­
tions of metallic additive. Risk of engine
damage!
- High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
- You can use higher octane fuel than your en­
gine requires.
- In countries where sulphur-free fuel is not
available, you may use low-sulphur fuel in­

stead.

Diesel fuel
Applies to: vehicles with diesel engine
Please note the information on the inside of the
fuel tank flap.
The use of sulphur-free diesel complying with
the EN 590 standard is recommended.
Diesel can thicken at very low temperatures,
which can result in problems starting the engine
or prevent the engine from running smoothly.
For this reason, filling stations in some countries
offer winter-grade diesel fuel during the cold
289

Checking and topping up fluids
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
© CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if
you
fill up with the
wrong type of
fuel,
as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.

When the automatic filler nozzle is operated cor­
rectly
it
will switch itself off
as
soon as the tank
is
fulL.
Do not try to put in more fuel after the
nozzle cuts out, as this will fill the expansion
chamber in the fuel tank.
The correct fuel grade for your vehicle is given on
a sticker on the inside of the tank flap. Further

A WARNING
Fuel is highly inflammable and can cause
seri­

ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and Leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or
a
spare fuel canis­
ter with
fuel,
do not smoke and keep away
from naked flames
-
risk of explosion!
- If, in exceptional circumstances, you have
to

carry
a
spare fuel canister, please observe
the following warnings:
- Never
filL
fuel into the spare fuel canister
with the canister placed in or on top of the
vehicLe. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite
-
risk of explosion! Always
place the canister on the ground to fill
it.

- Insert the filler nozzle as far as possibLe
into the spare fuel canister.
-
If
the spare fuel canister is made of metal,
the filler nozzle must be in contact with
the canister during filling. This helps pre­
vent an electrostatic charge building up.

- Make sure you never spill fuel in the
vehi­

cle or in the luggage compartment. Fuel
vapour is explosive - danger to life!
© Note
(7) CAUTION
- If any fuel is spilt onto the vehicle, it should
be removed immediately as it could other­
wise damage the paintwork.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc­
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
catalytic converter(s).
- Applies to vehicles with diesel engine: When
filling the fuel tank after having run it com­
pletely dry, the ignition must be switched
on for at least 30 seconds before the engine
is started. When you then start the engine it
may take longer than normal (up to one mi­
nute) for the engine to start firing. This is
because air needs to be bled from the fuel
system while starting.
® For the sake of the envir
Do not try to put in more fuel after the auto­
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm.

(T)
Note
Applies to: vehicles with diesel engine
Diesel vehicles are equipped with an incorrect
fuelling protection
system1).
This system en­
sures that the tank can only be fuelled from a
diesel filler nozzle.
- If the filler nozzle is old, damaged or too

small,
it may not be able to open the pro­
tection mechanism on the fuel tank. In this

case,
try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ­
ent filling pump or seek professional assis­

tance.

- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. You can get round this simply by adding
the diesel fuel slowly.

Checking and topping up fluids
Selective catalytic
reduction (AdBLue/DEF)
General notes
Applies to: vehicles with selective catalytic reduction
On vehicles with selective catalytic reduction, a
urea solution (AdBLue/DEF) is injected into the
exhaust system upstream of
a
NOx catalytic
con­

verter in order to reduce nitrogen oxide emis­

sions.
The urea solution is known under the name
of AdBlue or DEF (Diesel Exhaust Fluid). The term
AdBlue is used below.
The AdBlue is held in a separate tank on the
vehi­

cle.
AdBlue consumption is approximately 1.0 -
2.5% of diesel fuel consumption.
As soon as a message appears in the instrument
cluster display reminding you to refill AdBlue,
you must refill the AdBlue tank or have this done
by
a
qualified workshop
^>page
293.
Checking the remaining range
The remaining (estimated) range for the current

AdBLue
level can be displayed on the on-board
